Description
The AFE5804 is a complete analog front-end device specifically designed for ultrasound systems that require low power and small size. The AFE5804 consists of eight channels, including a low-noise amplifier (LNA), voltage-controlled attenuator (VCA), programmable gain amplifier (PGA), low-pass filter (LPF), and a 12-bit analog-to-digital converter (ADC) with low voltage differential signaling (LVDS) data outputs.
